jQuery replace an image on click

jQuery replace an image on click- example below, this is a method to swap numerous images in HTML by manipulating the images src attribute value from the click of another element such as a button.

Black Image

HTML

<div class="button-container">
<button class="black-button"></button>
<button class="red-button"></button>
<button class="blue-button"></button>
<button class="yellow-button"></button>
</div>

<img id="change-image" src="/wp-content/uploads/2018/09/black.jpg" alt="Black Image" />

jQuery

jQuery(document).ready(function($){

$('.black-button').on({
     'click': function(){
         $('#change-image').attr('src','/wp-content/uploads/2018/09/black.jpg');
     }
 });
 
$('.red-button').on({
     'click': function(){
         $('#change-image').attr('src','/wp-content/uploads/2018/09/red.jpg');
     }
 });
 
$('.blue-button').on({
     'click': function(){
         $('#change-image').attr('src','/wp-content/uploads/2018/09/blue.jpg');
     }
 });
 
$('.yellow-button').on({
     'click': function(){
         $('#change-image').attr('src','/wp-content/uploads/2018/09/yellow.jpg');
     }
 });
});

Each button's CSS class is targetted on click which then targets the ID of the image that changes the src attribute of the image.

This uses jQuerys attr() method which can change the value of a given attribute - so also here the alt text value can be changed for each image.
